BD4WCL The overall loss of a full-sized GP antenna is not significant, but due to its antenna characteristics, it has high baseline noise. If your electromagnetic environment is poor, this baseline noise will overwhelm and mask the weak signals you are trying to receive. Secondly, the low elevation angle of a GP antenna makes it suitable for long-distance communication. However, even with ideal conditions (favorable terrain, weather, and human factors), long-distance communication still requires overcoming challenges. For example, if you use a high-angle antenna at your radio station to transmit, and someone else is receiving your signal using a low-angle antenna, they may be able to receive the signal, but as the distance increases, it becomes increasingly difficult for them to hear. They will still perceive that they cannot connect to the radio station.
